The Blueprint Analog Atmosphere Controller controls up to four 120V devices, with dedicated receptacles for cooling, humidity and CO2. A remote sensor on a 15’ cable accurately monitors temperature, humidity and light. The one-button display is easy to operate, and the three modes allow temperature and humidity to be controlled together or separately. The temperature control range is 41-113°F with a 3°F deadband, and the humidity control range is 5-95% RH with a 5% RH deadband. The Controller is ETL listed and comes with a three-year warranty.
